How do you do the following?

1. Let x take the values between −6π and 6π.

2. Use the for loop to calculate the sin(x). Store the results in y.

3. plot y vs. x.

4. Find the minimum point of sin(x) in this range of the values of x. Hint: use fminbnd. You may read about fminbnd by typing help fminbnd in the command window.

Answer 1

[madhan ravi]

1) Define x using increment.

2) Just use a for loop.

3)Use plot(...).

4)Use fminbnd(...) by parametrizing the function.

Answer 2

[KSSV]

m = 100 ;
x = linspace(-6*pi,6*pi,m) ;
y = zeros(size(x)) ;
for i = 1:m
    y(i) = sin(x(i)) ;
end
    

It is your job to do the rest. Read about min and fminbnd
